Users can request FEBio to output a binary dump file. This dump file can be used to restart the analysis from the time point saved in the dump file. The user can restart the analysis either directly from this binary dump file or via a restart input file, which is described in this chapter. See section 2.8.4↑ for more information on how to use the restart feature.

LoadData redefine or add some loadcurves.
Step add an analysis step.
All sections are optional except for the Archive section. In the following paragraphs we describe the different sections in more detail.
